AIMS/BACKGROUND To describe a bilateral, mid peripheral, ring-shaped corneal opacity, not resembling any known corneal degeneration, dystrophy, or other disorder, and occurring without ocular or systemic disease. METHODS Ophthalmic examination, haematological screening, and ultrasound biomicroscopy. RESULTS A 25 year old man showed grey-white, granular opacities in both corneas, with an 8 mm diameter ring configuration, and a V-shaped distribution in the anterior stroma. The surrounding corneal stroma was clear, and the tear film, the epithelium and its basement membrane, Descemet’s membrane, and the endothelium were normal. Evidence of systemic disease was not found. Family members did not show corneal abnormalities. CONCLUSION A bilateral corneal ring opacity may occur in healthy, asymptomatic, young people. These corneal rings may result from depositions of unknown origin, or possibly a rare corneal dystrophy.
